Is 3 a factor of 245 - 16? yes no HELPPP

Mathematics
1 answer:
telo118 [61]2 years ago
5 0

Answer:

No

Step-by-step explanation:

For 3 to be factor your finale number has to be divisible by 3, so with that information all you have to do is subtract 245-16 which is 229, and if you divide 229 by 3 it does not equal a whole number so 3 cannot be a factor.

I hope this helps, and have a great day! :D

If y varies directly as x and x=2 when y=−4, find y when x=−6.
kakasveta [241]

Answer:

Equation: x × -2 = y

Solution: y = 12

Step-by-step explanation:

if (x = 2) is (y = -4) then (x = 1) is (y = -2) so if (x = -6) is (y = 12) if we follow the equation [x × -2 = y] which was found using the first set of variables and dividing each by 2.

Noah and Lin are each trying to solve the equation x² - 6x + 10 = 0. They know that the solutions to x² = - 1 are i and -i, but
Leviafan [203]

Answer:

Solving the equation x^2 - 6x + 10 = 0 we get x=3+i \ , \ x=3-i

Step-by-step explanation:

Noah's step to solve the equation x^2 - 6x + 10 = 0 are:

x^2 - 6x + 10 = 0\\x^2 - 6x = -10\\x^2 - 6x + 9 = -10 + 9\\(x-3)^2 = -1

The next step is to take square root on both sides because: \sqrt{x^2}=x

\sqrt{(x-3)^2}=\sqrt{-1}  \\x-3=\pm\sqrt{-1} \\x=\pm(\sqrt{-1})+3 \\

Now, we know that: \sqrt{-1}=i

x=\pm(i)+3\\x=3+i \ , \ x=3-i

So, Solving the equation x^2 - 6x + 10 = 0 we get x=3+i \ , \ x=3-i
